NEW YORK, May 11 (Reuters) - A slide in oil prices on Wednesday sparked a second big rout across commodities in less than a week, driving investors away from riskier investments like stocks.
Crude oil prices tumbled by more than 3 percent, driving New York crude below $100 a barrel, stung by a rise in crude oil inventories and signs that China's economy is cooling.
Other commodities also slumped, with spot silver
On Wall Street, all three major indexes fell more than 1 percent, led by losses in energy shares, while the dollar and U.S. Treasuries gained on a safe-haven bid.
Heightened worries about debt-stricken European countries drove down the euro, which hit a three-week low against the dollar.
"With the dollar continuing to strengthen, commodities like oil should continue to trade off given the inverse relationship between the dollar and some of these commodities," said Phil Orlando, chief equity market strategist, at Federated Investors in New York.
"All these different issues -- currencies, the commodities, equity prices, the risk trade -- all seems to be somewhat interrelated."
Brent crude was down $3.96 at $113.67 a barrel, while U.S. crude futures tumbled 4.37 percent to $99.32.
The Dow Jones industrial average <.DJI> was down 150.95 points, or 1.18 percent, at 12,679.57. The Standard & Poor's 500 Index <.SPX> dropped 16.32 points, or 1.2 percent, to 1,340.84. The Nasdaq Composite Index <.IXIC> gave up 30.17 points, or 1.05 percent, at 2,841.72.
The market's decline was broad, with six stocks falling for every one rising on the New York Stock Exchange.
Oil related exchange traded funds fell sharply.

DEBT WORRIES DOG EURO
New outbreaks of unrest in Europe highlighted the worries over debt-laden peripheral nations.
The euro hit a session low of $1.4275
The European peripheral nations "have never had their fiscal house in order," said John Doyle, strategist at Tempus Consulting in Washington. Investors "may have lost focus on that but it is now back in focus."
In Greece, police fired teargas at dozens of youths hurling stones in central Athens on Wednesday and a strike against austerity brought much of the nation to a halt during talks on the next slice of a bailout package. [ID:nLDE74A0SY]
EU finance ministers will discuss Greece's debt crisis next week but will not decide on new emergency aid until a mission to Athens that began on Wednesday gives its verdict on progress on reforms. For details, see [nLDE74A0SY]
Ministers are likely to tell Greece it must deliver on savings and privatization targets already agreed if it wants new emergency financing next year, a euro zone source said.
Meanwhile, Portugal hopes its bailout plan will be approved on Monday and looked set for a green light from a key German parliamentary panel. [ID:nLDE74A16A]
CHINA ECONOMY SLOWING?
Data out of China showed the country's industrial input growth eased much more than expected in April, reducing the need for further aggressive monetary policy tightening even as inflation remains stubbornly high. [ID:nL3E7GB0H2]
World stocks as measured by the MSCI stock index <.MIWD00000PUS> were down 0.8 percent. European shares held onto gains to end higher as strong corporate results there offset euro zone jitters. The FTSEurofirst 300 index <.FTEU3> provisionally closed up 0.3 percent. (Additional reporting by Rodrigo Campos and Nick Olivari; Editing by Leslie Adler)
